THERMAL SHOCK RESISTANT MEMBER
To provide a thermal shock resistant member sufficiently exhibiting mechanical strength and thermal shock resistance of ZTA.SOLUTION: A thermal shock resistant member according to the present disclosure comprises a ceramic containing aluminum oxide as a main component, zirconium oxide, and a closed pore area ratio of 10% or more and 20% or less. In the ceramic, a difference (A) between the average value of the distance between the centers of gravity of the adjacent zirconium oxide crystal particles and the average value of the circle equivalent diameter of the zirconium oxide crystal particles is 0.7 to 1.3 times a difference (B) between the average value of the distance between the centers of gravity of the adjacent closed pores and the average value of the circle equivalent diameter of the closed pores.SELECTED DRAWING: None
【課題】ＺＴＡが有する機械的強度および耐熱衝撃性を十分に発揮し得る耐熱衝撃性部材を提供すること。【解決手段】本開示に係る耐熱衝撃性部材は、酸化アルミニウムを主成分とし、酸化ジルコニウムを含み、閉気孔の面積率が１０％以上２０％以下であるセラミックスを含む。セラミックスにおいて、隣り合う酸化ジルコニウムの結晶粒子の重心間距離の平均値と酸化ジルコニウムの結晶粒子の円相当径の平均値との差（Ａ）が、隣り合う閉気孔の重心間距離の平均値と閉気孔の円相当径の平均値との差（Ｂ）の０．７倍以上１．３倍以下である。【選択図】なし
